Brief Summary

Sixteen million babies were born in 2010, approximately half were by cesarean. Labor analgesia should be the first choice for these parturients based on the consideration of security and humanization. However this labor analgesia rate is quite low in China (\<5%) while in western country, this rate is up to 60%. Programmed intermittent epidural bolus (PIEB) is the latest technique for labor analgesia which has less neurotoxicity theoretically compared with Continuous Epidural Infusion(CEI) with Patient controlled epidural analgesia (PCEA) which is used most commonly. In that study, they reported less total local anesthetic consumption, fewer manual bolus doses and greater patient satisfaction with the PIEB technique. In China, multiple factors contribute to the reasons of low labor analgesia rate. From the patient's point of view, worrying about unsatisfied analgesia, and not adapted to the symptoms of motor block, such as inability to move their legs distressing, both are important reasons of refusing labor analgesia and preferring to cesarean delivery. Therefore, in this clinical trial, we plan to find a safer and more effective regimen for labor analgesia in Chineseparturients. This clinical trial is designed to prove PIEB used Ropivacaine is safer and more effective than CEI for labor analgesia in Chinese parturients.

Outcome Measures

Primary Outcomes (1)

  • Maternal visual analogue scale (VAS)

    a visual analog scale (VAS) with a 10 cm vertical score ranged from "no pain" to "worst possible pain"

    At time of initiation of analgesia and hourly thereafter until 1 hours postpartum (approximately 10 hours)

Secondary Outcomes (17)

  • Maternal modified Bromage scale

    At time of initiation of analgesia and hourly thereafter until 2 hours postpartum (approximately 10 hours)

  • Subject's Satisfaction with labor epidural analgesia

    At the time after childbirth

  • Total ropivacaine and sufentanil consumption

    At two hours postpartum

  • Proportion of parturients requiring additional PCEA boluses

    At two hours postpartum

  • Rate of "very satisfied"and/or "satisfied",Proportion of subjects who has experienced Visual analog scale (VAS) score for pain more than 3 scale

    At two hours postpartum

  • +12 more secondary outcomes
